Comparison of geometry minimizations of the six starting configurations of histidine residue 4 in chain A of PDB entry 4rj2. The left column allows the planar torsion to relax, whilst the right column maintains the starting position. The top views are perpendicular to the ring, with the bottom views showing the ring on edge. Note that the atoms from the main-chain CA atom to the CG atom are frozen in both cases.
